From what I understand, this mouse still has one physical button, but uses the touch sensors to detect which side of the mouse you hit. The problem I see with this is that most people I know rest one finger on each of the two mouse buttons (and right click with my middle finger), so the sensor would not know if I intended to right or left click. This would only work for people who click with only their index finger.

It also looks like the mouse has a built-in speaker for simulating the sounds of scrolling and clicking. I sincerely hope that this can be turned off. The only advantage of touch sensors over mechanical buttons is that they are silent, and I would not be willing to give up extremely useful tactile feedback if I now have to listen to pre-recorded scrolling sounds.
